How Do Bidets Get Warm Water? A Detailed Breakdown

Nothing wakes you up like cold bidet water in the morning. While some people don’t mind the frigid bidet water, others prefer a bit of warmth when they clean up. Warm-water bidets are very common, but they require a few plumbing differences compared to cold-water bidets.

Bidets get warm water by connecting to the hot water plumbing lines, but some models have heated water tanks. Many warm-water bidets let you adjust the temperature with a thermostat or a knob to control the heat output. These bidets require more plumbing since the water has to be heated.

Warming your bidet water can make morning toilet trips a bit less daunting. There are many ways to make your bidet use warm water, all of which are worth it during the cold winter months.

Can You Make Bidet Water Warm?

You can make bidet water warmer by plumbing it into a hot water line. Adjust the temperature with the thermostat knob to find the perfect setting for your bathroom needs. Remember, cold water bidets don’t have access to the hot water heater, so you’re stuck with the ambient water temperature in your home.

Let’s explain the three main ways you can make bidet water feel warmer:

1. Get a bidet with a hot water tank. These bidets aren’t the most popular choice because they have large tanks that take up space. That being said, they have the significant advantage of always having hot water ready to use rather than having to wait for it to get warm.
2. Choose a bidet attachment that connects to an electricity supply. These bidets provide hot water relatively quickly. Their downside is that you need an electrical outlet nearby, which can be a bit of a hassle in the bathroom. However, they’re tankless and often include thermostats.
3. Try a bidet or a bidet attachment that goes in line with the water heater. Bidet attachments are my favorite options because they’re easy to install, inexpensive, and don’t take up much space on the toilet. Connect a warm water bidet to your hot water line and you’ll be good to go.

Using a bidet to clean the front with warm water makes it a lot less uncomfortable. I’ve used my bidet on cold mornings far too many times to count, and it’s never a fun experience. However, it’s not much of an issue for people who live in warm climates or those with warm water bidets.

Another option is to improve a space heater and place it in your bathroom for a few minutes before you use the toilet. While it might not make the bidet water warmer, it’ll make your bathroom visits less chilly. You could also get a heated toilet seat (stay away from the seat covers because they harbor bacteria).

Does a Warm Water Bidet Use Electricity?

Warm water bidets can be installed with electricity if they have water tanks or thermostats. You can also install mechanical, non-electric bidets that use water pressure coming from a hot water line. Most warm water bidets use between 600 watts to 1400 watts for a few seconds, so they’re fairly energy-efficient.

Bio Bidet shows you have to connect a non-electrical warm water bidet to your sink’s hot water line. While this might seem tedious, it prevents you from needing to run wires or cables in the bathroom. Additionally, it’s very convenient for bidet attachments on toilets right next to the sink.

The LUXE Bidet Neo 320 is a non-electric hot water bidet that includes a temperature adjustment knob. It sits under your toilet seat, but the controls are on the right side of the toilet. You can change the water temperature, pressure, and location. They come in blue, rose gold, and white to match your bathroom’s color scheme.

The best thing about bidet attachments is that these bidets don’t require special plumbing, water lines, and so on. You can find bidet attachments with electric or non-electric warm water nozzles. You could also choose a manual bidet nozzle that connects to the side of your toilet.

Why Is Your Bidet Water Not Hot?

Your bidet hot water isn’t hot because there’s a leak, it has a broken thermostat, or something’s wrong with the hot water heater. Some bidets take longer to heat the water when it’s cold outside, so it might take a few seconds to heat up.

Try these suggestions to fix your bidet’s hot water issue:

• Use Teflon tape to seal all of the connection points in your bidet’s plumbing. The only time you don’t need to use Teflon tape on a bidet’s hoses is when there’s an O-ring or silicone sealant.
• Check your hot water heater to make sure the thermostat is high enough. Some water heaters take longer to heat up.
• Turn off other water utilities using hot water (sinks, showers, dishwashers, etc.). These utilities pull from the same water heater as your bidet, so they’ll limit the warm water supply.
• Bidet King explains you should turn off your bidet’s eco mode because it can prevent it from using enough energy to heat the water. Most bidets don’t have eco modes, but it’s worth looking into if you have an advanced bidet.
• Adjust your bidet’s heating knob to the highest setting if it’s cold outside. Bidets are a lot like showers and sinks because they don’t immediately go to the hottest setting when they’re on a high temperature. They take a little while to heat up, but since you’re only running the bidet for half a minute or less, you might not feel the warmth.

Dirty water in your plumbing can also stop your bidet from supplying warm water through the dispensing nozzles. The same issue happens when your humidifier has dirty water. The water outlet has to be cleaned, which also includes turning on the self-cleaning mechanism after each use of the bidet.

Your water heater could also be at fault. While it doesn’t apply to bidets with warm water tanks, a faulty hot water heater will undoubtedly limit your tankless bidet’s capabilities. Tankless water heaters take longer to heat up when it’s cold outside, so that could affect your bidet’s water temperature.
